To aZZ whom it may concern: per end an arm 10 which extends through an Be it known that I, JAMES M. MONTGOM- l opening in the stop strip. The outer pro- ERY, a citizen of the United States, residing jccting arm 10 is apertured to receive one of at Berl, in the county of Mineral and State of the terminals of an electric circuit 12. The West Virginia, have invented certain new I cam lever 5 is pivoted by a screw or the like and useful Improvements in Combined Burj 13 upon the side of the stop strip 2, at a suitglar Alarms and Sash-Holders; and I do dej able point above the top of the sash frame clare the following to be a full, clear, and-exand 'it consists of a cam proper 14 which is act description of the invention, such as will formed with an integral handle or lever enable others skilled in the art to which it The cam 14 is of elongated circular form and appertains to make and use the same. has its edge faced with rubber or other suit- My invention is an improved combination able material .16 which projects beyond the window sash fastener and circuit closing de edge of the cam and is adapted to frictionvice for burglar alarms, and it consists in ally engage the outer face of the vertical the novel construction, combination and arside bar of the sash frame 3 to retain it at rangement of parts hereinafter described and any desired elevation. The pivot screw 13 claimed. passes through a centrally arranged opening The object of the invention is to provide a 17 in the cam, so that when the sash 3 is in simple, practical and efficient window sash its lowered position shown in Fig. 2 and the fastener which may be used for holding the cam hangs in its normal position shown in sash at any adjusted position or looking it said figure, one end of the cam will project closed, and which will also serve to close an over the top edge of the sash 3 and the porelectric burglar alarm circuit. tion or arm 8 0f the plate 7 and prevent said The above and other objects which will sash from being elevated. appear as the nature of the invention is bet- WVhen the handle 5 of the cam is swung at ter understood, are accomplished by means right angles to the strip 2, the narrow portion of the construction illustrated in the accomof the cam will extend inwardly, so that the panying drawings, in which sash 3 may be raised or lowered as desired, Figure 1 is a diagrammaticview showing and when the handle 15 is swung upwardly my improved device applied to a window to a greater extent so that the other half of and connected up with a burglar alarm cirthe cam is brought into frictional contact cuit; Fig. 2 is a side view of a portion of a with the outer face of the vertical bar of the Window frame, showing my improved comsash frame 3, the latter may be frictionally bination sash fastener and circuit closer apclamped at any desired height, as will be plied thereto and to the lower sash; Fig. 3 is readily understood. The rubber facing 16 a detail sectional view taken on the plane inupon the cam will firmly engage the sash dicated by the line 33 in Fig. 2; Fig. 4 is a frame and prevent the latter from dropping. detail view of the cam lever of the device, The other terminal of the electric circuit 12 and Figs. 5 and 6 are perspective views of is connected to the pivot screw 13, so that the two contact plates of the device. the circuit will be closed whenever the sash Referring to the drawings by numeral, 1 frame 8 is elevated sufliciently to cause the denotes a portion of a window frame, 2 the contact plate 7 to engage the cam lever 5. usual stop strip secured thereto, and 3 the When the parts are in the position shown in lower vertically sliding Window sash. My Fig. 2 of the drawings, the contact plate 7 is but about a sixteenth of an inch from the cam 5, so that the slightest upward movement of the sash frame will close the circuit. The circuit 12, as shown in Fig. 1, includes a battery or other generator 18 and an electric bell or other suitable signal 19.
From the foregoing description taken in connection with the accompanying drawings, the construction, operation and advantages of the invention will be readily understood combined sash fastener and circuit closer 4 consists of a cam locking lever 5, and two contact plates or strips 67. The latter 7 is of right angular form and has its short end 8 secured upon the top of the sash 3 adjacent to one of its ends, and its long arm 9 secured upon the outer face of the sash 3 and adapted to contact with. the other plate 6. This plate 6 is secured upon the inner edge of the stop strip 2, and has projecting from its up- ICC . and a sliding sash, of the plate 7 secured upon Without requiring a more extended explanation.
Various changes in theform, proportion and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of the invention, as defined by the appended claims.
Having thus described my invention, What I claim as neW and desire to secure by Let ters Patent is 1. The combination With a Window frame and a sash, of coac'ting contact plates secured upon said frame and sash, a cam upon said frame for coaction With said sash and adapted to project into the path of one of said contact plates, and an electric circuit having one of its terminals connected to the other of said contact plates and the other of its terminals to said cam.
2. The combination With a Window frame upon said frame and adapted to have its opposite' ends coact with said sash, one of said ends hanging normally in the path of the contact plate 7, and an electric alarm circuit having one of its terminals connected to the contact plate 7 and its other to said cam, substantially as shown and described.
3. The combination with a Window frame and sash of co-acting contact plates secured upon said frame and sash respectively, a sash locking member adapted to project into the path of one of said plates, and an electric circuit having one terminal connected to the other of said contact plates and With its other terminal connected to said locking member.
In testimony whereof I have hereunto set my hand in presence of tWo subscribing Witnesses. I
JAMES M. MONTGOMERY. Witnesses:
said sash, the plate 6 secured upon said frame, the elongated cam 5 pivoted at its center ARTHUR G. RICHARD, FRANK D. MULLEN.
